Product Description

 

 

Transform your Porsche 981 Cayman GT4 or Boxster Spyder into a true motorsport-inspired machine with the Fabspeed Race Headers. Designed for maximum performance on the track, these catless long-tube headers replace the restrictive factory exhaust manifolds with a high-flow equal-length design engineered to maximize exhaust velocity, improve scavenging, and unlock additional power from Porsche’s naturally aspirated flat-six engine. Featuring Fabspeed’s high-velocity merge collectors and CNC mandrel-bent T304 stainless steel tubing, these headers optimize exhaust pulse tuning for improved torque delivery throughout the RPM range. The result is a dramatic increase in throttle response, stronger acceleration out of corners, and a more aggressive race-bred exhaust note that matches the GT4’s performance-focused character. Designed for track and off-road applications, these headers are the ultimate upgrade for enthusiasts looking to extract maximum performance from their 981 GT4 or Spyder.
